Automated library distribution to Maven

Slides from my talk at GDG Brussels February 2016

Comprehensive talk about library distribution to either a public or private Maven repository, including topics such as:

- Introduction to Maven
- Maven adoption by Android
- Distributing to JCenter
- Distributing via JitPack
- Setting up your own Maven repository (Artifactory)
- Using Git as a Maven repository

Transcript

1. AUTOMATED LIBRARY DISTRIBUTION TO MAVEN @MOLSJEROEN
2. BEFORE SOFTWARE CAN BE REUSABLE IT FIRST HAS TO BE USABLE. Ralph Johnson
3. MAVEN FUNDAMENTALS
4. @MOLSJEROEN WHAT IS MAVEN ▸ Build automation tool 1. Describes how software is built ‣ default conventions ‣ specify all exceptions 2. Describes dependencies ‣ locally installed repository ‣ remote Maven repository
5. @MOLSJEROEN HOW MAVEN HANDLES DEPENDENCIES ▸ Release identified by ▸ GroupId com.jeroenmols ▸ ArtifactId landscapevideocamera ▸ Version 1.1.3 ▸ Multiple artifacts possible ▸ Library landscapevideocamera.aar ▸ Documentation javadoc.jar ▸ Sources sources.jar
6. @MOLSJEROEN HOW MAVEN STORES DEPENDENCIES
7. @MOLSJEROEN IMPORTANT CONSIDERATIONS ▸ Maven can only be used if: ▸ Repository reachable and online forever ▸ Existing artifacts never modified ▸ New versions come from same developer ▸ Code must always build immediately after checkout ▸ When doubt: add artifacts to version control
8. @MOLSJEROEN ADOPTION BY ANDROID ▸ Gradle ▸ Specify Maven repositories to use ▸ Define dependencies (and configuration) ▸ Upload your own artifacts ▸ Local maven repository ▸ Support libraries ▸ Google play services
9. @MOLSJEROEN GRADLE - USE MAVEN ARTIFACTS allprojects {
 repositories {
 jcenter()
 maven { url “http://mywebsite.com/mavenrepository" }
 }
 } dependencies {
 compile fileTree(dir: 'libs', include: ['*.jar'])
 compile ‘com.android.support:appcompat-v7:23.1.0’ 
 compile ‘com.jeroenmols:landscapevideocamera:1.1.3'
 }
10. @MOLSJEROEN GRADLE - USE MAVEN ARTIFACTS allprojects {
